When other risk factors for NAION are present, taking blood pressure medications at night should be avoided as this can exacerbate nighttime hypotension. Beta blockers in particular are associated with increased incidence of NAION. [4] These vascular risk factors lead to ischemia (poor blood supply) to a portion of the optic disc.
Key risk factors include coronary artery disease, cerebrovascular disease, sleep apnea, diabetes, and hypertension. Currently, there is no universally accepted, scientifically proven treatment for NAION. However, there is a general consensus on the importance of managing underlying risk factors to prevent further complications.
Ischemic optic neuropathy (ION) is the loss of structure and function of a portion of the optic nerve due to obstruction of blood flow to the nerve (i.e. ischemia).Ischemic forms of optic neuropathy are typically classified as either anterior ischemic optic neuropathy or posterior ischemic optic neuropathy according to the part of the optic nerve that is affected.
The American study found that Ozempic more than doubles the risk of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition that damages the optic nerve.
Non-arteritic anterior ischemic optic neuropathy, or NAION, is a condition that affects the optic nerve, a bundle of fibers that connects to the back of the eye and carries signals to the brain so ...
Optic nerve damage. ... (non-arteritic anterior ischemic optic neuropathy) ... It’s also worth noting that NAION appears to occur mostly in people with a pre-existing risk factor for eye damage ...
In contrast, anterior ischemic optic neuropathy (AION) is distinguished from PION by the fact that AION occurs spontaneously and on one side in affected individuals with predisposing anatomic or cardiovascular risk factors. [citation needed]
Ischemic optic neuropathies are classified based on the location of the damage and the cause of reduced blood flow if known. [3] Anterior ischemic optic neuropathy (AION) includes diseases that affect the optic nerve head and cause swelling of the optic disc. These diseases often cause sudden rapid visual loss in one eye.
